There has been much speculation out there. But Rival Software which
ironically is based out of Canada has never stated why.

From my understanding, it has to do with a breach of contract from
2006 from a marketing company located in Canada against the
Rival Software company. Has something to do with the software
development. I thought that it was suppose to be settled in
court in late 2009. So if this is the case, then something
should be showing in the newswires shortly. ​
